The NPS cautioned that winter conditions still exist at higher elevations and said even the most experienced hikers can encounter dangerous challenges in the conditions.

Dokov’s death came just eight days after Eric Juliani, 29, of New Jersey, was killed while attempting to summit Mt. Whitney on May 5.

The NPS said Juliani was reported missing after he did not return from a solo summit attempt on the Mountaineers Route. Two hikers making their decent reported finding a trail of blood leading from two ice axes to a body about 1,500 to 2,000 feet below.
